Yamaha could make external control a lot easier, though...

A lot of things that you can control with CC's on most brands takes sys-ex strings on the Yamaha. And this is a LOT more difficult to program correctly, especially if a variable is involved (checksum calculations, anyone?!).

At some point or another, I simply wish the arranger manufacturers would get together and agree on a common set of CC's and codes to control most common arranger operation functions. Not only would this make external foot control easier, but also linking and running two arrangers as one large arranger.
